NAVIGATION DEVICE AND METHOD INTEGRATING MULTIPLE INERTIAL HYBRID NAVIGATION SYSTEMS

摘要

The present invention relates to a hybridized navigation device for a vehicle comprising at least one auxiliary sensor capable of delivering at least one auxiliary signal representative of a parameter and a plurality of hybridized navigation systems, each hybridized navigation system comprising at least one system inertial navigation system and at least one computer configured to hybridize at least one signal representative of an inertial measurement with said at least one auxiliary signal, to form a hybridized signal output from each hybridized navigation system. According to the invention, said hybridized navigation device comprises a module for detecting the proper functioning and weighting of said hybridized navigation systems, said module being configured to receive on the one hand said at least one auxiliary signal and on the other hand said hybridized signals of each hybridized navigation system and deriving therefrom at least one operational indicator and a weighting coefficient for each hybridized navigation system and calculating a weighted hybridized signal according to said hybridized signals and respective weighting coefficients of each hybridized navigation system.
